How to correct the shape of the separator in modeline, when using spaceline?

Question

My mode-line has problems when changing the shape of the separator, when using the spaceline package which has powerline as a dependency. It applies the change of shape of the separator but the colours are not right. Is there a way to fix this?

I am using vanilla emacs in GUI mode version 25.

Answer 1

It turns out to be a spaceline specific problem. I fixed it by adding the following settings.

(setq powerline-height 20)
(setq powerline-raw " ")
(setq ns-use-srgb-colorspace nil)
